New digital control systems open new possibilities in many areas. It is here presented design and implementation of a real-time optimal positioning and data collecting system in a newly designed laboratory wind tunnel. The wind tunnel has the possibility of changing the wind intensity in the tunnel. The control system positions the aerodynamic profile in different positions and measures the pressure along the profile in 14 points. All these data are stored in real-time in the SCADA system. This enables automatic finding of the optimum position of the profile according to various parameters: smallest resistance, maximum lifting force, smallest draft force and etc. It also allows students as well as researchers to view data in the form of graphs or tables in real-time as well as additional later offline process and review of the saved data.

As Networked Control Systems grow more complex in industrial applications, moving network modules and cabling decrease overall system reliability. This paper presents an FPGA-based fault tolerance technique to reduce cabling and increase the overall reliability of such a system. A sectored sensor-to-actuator networked control system architecture with sensor-level sift-out modular redundancy is modeled and analyzed. The fault models considered in this study are Single Event Upsets and hard failures. A reliability analysis is then conducted to evaluate the reliability of each block in the system and study the overall system reliability. A generic reliability analysis is presented to investigate the flexibility of the fault tolerance technique and a case study demonstrates the reliability improvements over a system that does not utilize FPGAs and cable reduction.

This paper presents the approach to finding the optimal path for the number of criteria in the transport network. The aim of the work is the development of the algorithm for finding the optimal path capable of solving this problem in the conditions of constantly changing external factors. As such factors, the most common metrics are chosen - travel time and throughput. As a mathematical model reflecting the dynamics of external factors, the tensor model is used. It is based on the dynamic Floyd - Warshall algorithm for finding the shortest distances between all the vertices of a weighted oriented graph. The developed algorithm is modified for the iterative analysis of paths in the graph and finding the optimal one with constant changes in throughput.

The Development of Information Technology and the Problem of Identity 信息技术的发展与身份问题
Pub Date : 2019-06-01 DOI: 10.1109/MECO.2019.8760159

The development of information technology has led to the emergence of such a social phenomenon as the information society. The article deals with the problem of the identity of a person who is forced to communicate with his own peers in the realities of the information society. As a philosophical explication of the latter is considered a poststructuralist concept of intertextuality. According to it an individual is a moving fragment of a continuously reproduced hypertext. In such a context semantic unity, treated by philosophical hermeneutics as a necessary condition for the identification of an individual as an understanding being, is an ideological projection. Poststructuralists postulate “natural” dispersion of the primary semantic unity. Henceforth, a person who has got stuck in the intertextual reproduction of communicative space and lost identity, participates in communication only as a producer of a new conceptual meaning. A message sent by such a person remains unanswered, which means the impossibility of communication in the information society. Since communication is an irreducible parameter of human existence, one should speak about an ideological deadlock of the concept of intertextuality and breakdown of an ideological construct of the information society.
信息技术的发展导致了信息社会这一社会现象的出现。这篇文章讨论了在信息社会的现实中,一个人被迫与他自己的同伴交流的身份问题。作为对后者的哲学解释,后者被认为是一个后结构主义的互文性概念。根据它,个体是不断复制的超文本的移动片段。在这样的语境中,被哲学诠释学视为个体作为知性存在的必要条件的语义统一是一种意识形态的投射。后结构主义者假定初级语义统一的“自然”分散。从此,一个陷入交际空间互文复制而失去身份的人,只能作为一种新的概念意义的生产者参与交际。这样的人发出的信息没有得到回复,这意味着信息社会中沟通的不可能。既然传播是人类生存的一个不可简化的参数,我们应该谈论互文性概念的意识形态僵局和信息社会意识形态建构的崩溃。

An Iris+Voice Recognition System for a Smart Doorbell 智能门铃的虹膜+语音识别系统

In this paper, we describe our methodology for designing a smart doorbell system for the homes. While the recent trend of big companies is to offer a home voice assistant, which can integrate all possible services, including the recognition of the owner (or authorized people) at the house door, privacy concerns and independence from a single service provider are requiring more freedom in the choice of the “smart objects” that surround us. The doorbell system is using both iris and voice recognition to verify the identity of the user who rings at the door. Since there is the involvement of biometric data, this information has to be properly handled. In particular, we designed our system in such a way that it can avoid to send or store any biometric data to the cloud. Machine-learning algorithms are used to perform local computations, thus implementing Edge-Computing analytics to determine the identity of the user, by combining both voice and iris biometrics. The system is implemented on reconfigurable hardware in order to accelerate some of the most intensive tasks and achieve enough performance at a reasonable power consumption. Our tests confirm that, by using our architecture, the performance is about 5x the sequential case and, at the same time, we reach about 7x less energy consumption.
在本文中,我们描述了我们为家庭设计智能门铃系统的方法。虽然大公司最近的趋势是提供家庭语音助手,它可以集成所有可能的服务,包括在房子门口识别主人(或授权人员),但隐私问题和独立于单一服务提供商的独立性要求我们在选择周围的“智能对象”时拥有更多的自由。门铃系统同时使用虹膜和声音识别来验证敲门者的身份。由于涉及生物特征数据,因此必须妥善处理这些信息。特别是,我们设计的系统可以避免将任何生物特征数据发送或存储到云端。机器学习算法用于执行本地计算,从而实现边缘计算分析,通过结合语音和虹膜生物识别技术来确定用户的身份。该系统在可重构硬件上实现,以加速一些最密集的任务,并在合理的功耗下获得足够的性能。我们的测试证实,通过使用我们的架构,性能大约是顺序情况的5倍,同时,我们达到了大约7倍的能量消耗。

Embedded Face Analysis for Smart Videosurveillance 智能视频监控的嵌入式人脸分析
Pub Date : 2019-06-01 DOI: 10.1109/MECO.2019.8760200
R. Giorgi, David Oro, S. Ermini, Francesco Montefoschi, A. Rizzo
In this paper, we describe our methodology for designing a smart Videosurveillance system for face analysis. The system aims at increasing the security by gathering demographic statistics in highly crowded areas such as train stations, airports and shopping malls. Based on Convolutional Neural Networks (CNNs), the system architecture relies on the reconfigurable hardware to accelerate part of the computation and reduce the power consumption compared to general-purpose processors and GPUs. To achieve easy programmability, the platform makes use of the OmpSs programming model, which provides parallelization and acceleration by using simple directives to be added to the sequential code. The rsource-intensive tasks are offloaded to the reconfigurable hardware in order to achieve the desired performance levels. Our evaluation shows that we can detect more than 600 faces per frame, while keeping the power consumption at about 8W. The tests were performed by using the AXIOM hardware/software platform.

The materiality of interaction - interaction design that moves beyond representation and metaphor to focus on the material manifestations of tangible interaction was explored in the context of tangible interface for intangible heritage. This article explores materialization of intangible heritage through tangible interactions. Some examples were designed for mixed reality exhibition “Archeology of memories and architecture of knowledge” which was shown at the Open days of science in Montenegro in October 2018. A new way of co-creation of knowledge was included, social sculptures, as long as audience was willing to augment themselves in narratives of intangible world heritage.
交互的物质性——在非物质遗产的有形界面的背景下,探讨了超越表征和隐喻的交互设计,关注有形交互的物质表现。本文探讨非物质遗产通过有形互动的物质化。其中一些例子是为2018年10月在黑山科学开放日展出的混合现实展览“记忆的考古学和知识的建筑”而设计的。一种新的共同创造知识的方式,社会雕塑,只要观众愿意在非物质世界遗产的叙述中增加自己。

A new way of co-creation of knowledge was included, social sculptures, as long as audience was willing to augment themselves in narratives of intangible world heritage.","PeriodicalId":141324,"journal":{"name":"2019 8th Mediterranean Conference on Embedded Computing (MECO)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131163569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present study a stress analysis on a deformed footprint was performed in the case when an anatomical customized insole is used and in the case when an anatomical customized insole is not used. For specific deformities of the foot, an anatomical insole is made by using EasyCAD software. Solid models of the foot and insole, which are necessary for creating finite element models, were obtained by scanning the physical objects of the footprint and insole, and by their reconstruction and optimization in Geomagic software. Stress analysis was performed in Catia V5 R21 software for the case of a neutral standing position on the ground. Results show maximum values of the pressures in the medial region of the foot and toe region in the case when an anatomical customized insole is not used. With the use of the customized insole, pressures are significantly reduced, both by size and region.
在本研究中,在使用解剖定制鞋垫和不使用解剖定制鞋垫的情况下,对变形的足迹进行了应力分析。对于特定的足部畸形,使用EasyCAD软件制作解剖鞋垫。通过扫描足部和鞋垫的物理对象,并在Geomagic软件中进行重建和优化,获得足部和鞋垫的实体模型,这是创建有限元模型所必需的。在Catia V5 R21软件中对地面中立站立的情况进行应力分析。结果显示,在解剖定制鞋垫不使用的情况下,足部和脚趾区域内侧的压力最大值。使用定制的鞋垫,压力显着减少,无论是尺寸和区域。
